Also today, Biden lays out a three-part vision, "A Plan to Put Work — and Workers — First," which he says is aimed at restoring the basic bargain we used to have in this country:

"First, we need to make sure hard-working Americans have the skills and opportunities to succeed in the jobs of the future."

"Second, we need to make sure people are paid fairly for their work. Those who work hard and do their part should share in the benefits, allowing them to earn a good living and get ahead."

"And third, we need policies that allow the middle class to maintain or improve their standard of living. A small pay raise doesn't help much if the costs of housing, health care, and education are rising significantly more."

P.S. Trumptweetsthis morning: "Crazy Joe Biden is trying to act like a tough guy. Actually, he is weak, both mentally and physically, and yet he threatens me, for the second time, with physical assault. He doesn’t know me, but he would go down fast and hard, crying all the way. Don’t threaten people Joe!"
